https://android-review.googlesource.com/175922 removed all uses
of system_server execmem and neverallowed it. The x86 emulator policy
inappropriately includes this rule. Delete it.
Fixes the following build breakage:
libsepol.report_failure: neverallow on line 473 of external/sepolicy/system_server.te (or line 12452 of policy.conf) violated by allow system_server system_server:process { execmem };
libsepol.check_assertions: 1 neverallow failures occurred
Error while expanding policy

When the toolbox domain was introduced, we allowed all domains to exec it
to avoid breakage. However, only domains that were previously allowed the
ability to exec /system files would have been able to do this prior to the
introduction of the toolbox domain. Remove the rule from domain.te and add
rules to all domains that are already allowed execute_no_trans to system_file.
Requires coordination with device-specific policy changes with the same Change-Id.

Size increase taken as a precaution against recent built breakage
due to lack of space on a number of targets (e.g. x86, ARM64).
System and user-data image sizes set to match currently most common
setup for the emulator: system image: 1.25gb, user-data image 700mb.

This fixes the issue with the emulator "-shell" option.
Init tries to open the console which is passed through
the kernel androidboot.console property, but fails to
open it because "avc" denies it. Init only has permissions
to open console_device in rw mode. This ensures that
/dev/ttyS2 is properly labeled as console_device.
Replaced tabs with spaces.

The goldfish-setup service (essentially /system/etc/init.goldfish.sh)
executes the following commands when certain conditions are met:
setprop ro.radio.noril yes
stop ril-daemon
so as to stop the RIL daemon and emulate a WiFi-only device. Both would
fail, though, because goldfish-setup does not have the permissions to
set relevant properties.
This CL modifies the emulator's SELinux policy to grant the necessary
permissions. It is a step towards fixing the ril-daemon-keeps-getting-
killed-and-restarted problem with the new ("ranchu") emulator, which
does not support telephony emulation yet. (The other step is to have
init start goldfish-setup, which will be done in a seperate CL.)

In goldfish kernel 3.10, the goldfish_tty device instantiates virtual
serial ports as /dev/ttyGF* (e.g. /dev/ttyGF0), not as /dev/ttyS* as in
goldfish kernel 3.4. However, in the emulator's SELinux security policy,
there is no specific security context assigned to /dev/ttyGF*, and the
one inherited from /dev (u:object_r:device:s0) prevents services such as
qemud and goldfish-logcat from reading and writing ttyGF*. Consequently,
qemud terminates abnormally on the classic x86_64 emulator:
init: Service 'qemud' (pid XXX) exited with status 1
Fix this issue by assigning /dev/ttyGF* the same security context as
/dev/ttyS*.

In goldfish kernel 3.10, qemu_pipe has been renamed to goldfish_pipe.
However, in the emulator's SELinux policy, there is no specific security
context assigned to /dev/goldfish_pipe, and the one inherited from /dev
(u:object_r:device:s0) prevents various processes (qemud, qemu-props,
etc.) from reading and writing goldfish_pipe. Consequently, the classic
x86_64 emulator will not boot if GPU emulation is enabled ("-gpu host"),
and does not render the UI correctly if launched with "-gpu off".
Fix this issue by assigning /dev/goldfish_pipe the same security context
as /dev/qemu_pipe.
This CL also benefits the new ("ranchu") emulator, where all supported
ABIs (arm64, mips64, x86 and x86_64) use 3.10-based kernels. Without
this fix, the new emulator boots and works, but there are avc denials
related to goldfish_pipe.
Last but not least, it is now possible to boot the classic x86 emulator
with a 3.10-based kernel instead of the current 3.4-based one, without
disabling SELinux.

Define BOARD_SEPOLICY_DIRS for the arm64, mips64, and x86_64
emulator targets. As a first cut, simply inherit from the
existing policy directories used for generic and generic_x86.
We may need further board-specific policy added for these targets
but testing will require first enabling SELinux in the relevant
kernel configs.

For ART testing, we need:
1) A larger userdata partition. A lot of files end up there as it
is multi-arch.
2) Don't strip prebuilts. Technically we only care about core-libart,
but this is the best high-level change that doesn't impact other
files.
